Copper(I) Complexes of Anionic Tridentate CNC Pincer Ligands

“…[3] Multi-dentate varieties of these, the first of which was reported by our group, [7] have also attracted significant attention as they hold several advantages over the mono-dentate versions such as the extra stability of metal adducts due to chelating effects, the capacity to protect large parts of the metal center from undesired side reactions and producing organometallic complexes with unusual properties and specific coordination geometries. [8,9] Among these, pincer carbene ligands are particularly interesting for their ability to force meridional arrangement at a metal site, and providing efficient catalysts for several transformations including C-C coupling. [10,11] This paper concerns the synthesis of a new mono-anionic, amido pincer with two pendent carbenes, and its utility in copper(I) chemistry.…”

Silver(I) and Nickel(II) Complexes with Oxygen‐ or Nitrogen‐Functionalized NHC Ditopic Ligands and Catalytic Ethylene Oligomerization

“…Following the report of the first complexes containing N-heterocyclic carbene (NHC) ligands [1] and the isolation of the first stable NHC ligands, [2] a fast growing interest developed for this class of ligands and their metal complexes, largely triggered by their often unique properties and wide range of applications. [3] Hundreds of ligands have been synthesized in which the NHC functionality is part of multidentate, homofunctional ligands [4] or of hybrid ligands, which associate at least two chemically different donor groups (e.g. NHC with nitrogen, phosphorus, oxygen or sulfur) within the same molecule.…”
